If you are skilled enough to actually clear hard content, you would have done so before the nerf rounds started and be on the next set of content.

Complaining in hindsight either means your skill is at least partially imaginary or you just like being a jerk to people who have run out of content at their skill level.

Either way it's significantly cheaper and smarter to use old content actually skilled people are done with as a way of expanding content for the next tier of skill down. From the context of some of these posts a few of you seem to want SE to risk shooting the game in the foot solely to justify your personal egos.
